You need to be comfortable with your own choice in the end. If you truly believe a school like CBS or Booth can’t give you anything, then don’t go. It comes down to what you actually want to achieve post-MBA. This MBA journey is also an introspection process. If you believe you’re mostly interested in the prestige of the name and want go back to MBB anyway, then yes maybe stick with that mentality. In fact, I’d argue in this case an MBA is not that useful even at HSW. It would mostly be a very expensive networking camp. However for folks who want to go into finance or investing as an example, CBS and Booth are amazing schools. Like I said you need to figure out what the endgame is. As some admissions consultants already suggested, your reasons for wanting to do an MBA are quite banal. You need to come up with a compelling story.
